Description |
| Apache
Axis to Deploy PB8 component and call from Java Client or PocketSOAP from
PB8 client |

calculator component running on Sybase EAServer as a Web service. Also covers
how to invoke web services from a PowerBuilder 8 client, using the PocketSOAP
SOAP client COM component.
|
| |
|
| Apache
Axis to Deploy PB9 component and call from JSP |

|
Instructions to get EAServer 4.0 or 3.6.1 installation up
and running with Apache SOAP 2.2 |
| |
|
| Apache Tomcat
with EAServer |
Although EAServer is a J2EE application server designed to
host both Web Components and Enterprise Java Beans, some users may wish
to use the Apache Tomcat engine as a Web Container, and delegate just the
EJB requests to EAServer. In this white paper and code sample, we show you
how to achieve just that.
|
| |
|
| Authentication
Service Demo |

for user configurable authentication service, and how it can be customized
to suit the security policy of the user environment
|
| |
|
| Authentication
via JAAS and JDBC Connection

Demonstrates how to use JAAS (Java Authentication and Authorization
Service) to authenticate our users against a database via a JDBC connection.
(For jagadmin it authenticates against EAServer). It is quite easy to replace
the user authentication piece with your own (or blank it out to give everyone
access).
|
| |
|
| Authorization
Service |
In this sample, the Java component writes authorization information,
including session, user, and role information to the Jaguar server log,
then allows access to proceed. The authorization component is invoked for
a PowerBuilder component, which is called from a PowerBuilder client application.
|
| |
|
| ClickStream

the scenes, allowing different types of component calls to be called genericallt
from JSP. The JSP uses the CTL to invoke an EJB component via JNDI, and
a PB component via CORBA |

response to stock price changes

JMS and servlet filters, and EJB container managed persistance (cmp 2.0).
The successful deployment of the Java PetStore 1.3 application clearly indicates
EAServer's ability to implement the new features included in the J2EE 1.3
spec and the ability to conform to the spec.

It provides a natural migration path for Web.PB applications, and a mechanism
for Jaguar components written in other languages such as Java or C++ to
return Web content to a browser.
|
| |
|
| Jaguar
Cookie Monster |
This utility is a Jaguar service that eats old cookies, keeping
your Jaguar repository to a manageable size. Every time the Jaguar server
is restarted, the CookieMonster browses the repository to find PowerBuilder
components, then "eats" outdated cookies that are unnecessarily
taking up space.
|
| |
|
| Java
Performance Monitoring API (JAMon) |
A free, simple, high performance, thread safe, Java API that allows developers
to easily monitor production applications. JAMon can be used to determine
application performance bottlenecks, user/application interactions, and
application scalability. JAMon gathers summary statistics such as hits,
execution times (total, average, minimum, maximum, standard deviation),
and simultaneous application requests.

Notification Listener |
Obtains an RMI connection to the JMX MBeanServer, and listens
for JMX notifications generated by the ServicesManager MBean, which are
sent whenever a service MBean changes state, or an operation is performed
on it. For example, if EAServer is shut down (or crashes), this generates
events that are picked up by the sample. |

a browser using a Servlet. You choose the log file you want to view from
a menu. The log file will be positioned at the end of the page so you
can see the last messages written. By simply reloading or refreshing the
page you get an updated view of the log.
|
| Simulating
Server Push in PB and EAServer |
A client application cannot pass a PowerBuilder object reference
to EAServer. But, this behaviour can be simulated by using a shared object
on the client to communicate with EAServer. To simulate server push, the
client uses the SharedObjectRegister and SharedObjectGet functions to create
a shared object. Once the object has been created, the main thread on the
client makes an asynchronous call to a method on the shared object, passing
it a callback object that should be notified when processing has finished
on the server. The method on the shared object makes a synchronous call
to the EAServer component method that performs processing
|
| SOAP
Development with PowerJ 4.0 and PowerBuilder 8.0 |
Whitepaper provides an introduction to SOAP, with corresponding
code examples including a PowerBuilder component to use as a Web Service
in EAServer, and a Java SOAP client.

sample application - Canine Shelter |
For EAServer 4.1 and 4.2. Demonstrates how a client application
would use the Sybase ClientProxy to construct and send a SOAP request to
an EAServer server. The ClientProxy hides all the details of SOAP processing
and HTTP and HTTPS transport, allowing the client programmer to concentrate
on client business process. The sample application is a Canine Shelter search
that sends a SOAP request for dog records that contain information matching
the search criteria entered by the user.
